MIXING-1VIAGHINE 7 Specification of Letters Patent. 7

Application filed September 25, 1919. Serial No. 326,267..

To all whom it may concern:

Be it known that I; CLARENCE G. l/VYATT, a citizen of the United States, residingat Camden, in the county of Cmden and State of New Jersey, have invented certain new and useful Improvements in Mixing-Machines, of which the following is a specification.

One object of my invention is to provide a mixing machine which can be conveniently used for quickly mixing paints or other materials.

Another object is to so construct my improved mixing machine that it can be readily transported and can be easily operated.

A further object is to make my improved machine of a comparatively simple and durable construction and so that it can be easily and quickly manufactured.

These ob-ects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which- Figure 1 is a front elevation of my improved mixing machine,

Fig. 2 is a top plan view of Fig. 1,

Fig. 3 is a sectlonal elevation taken on the line 33 of Fig. 2,

v Fig. 4 is an end view looking in the direction of the arrow w in 1, and

Figs. 5, 6 and 7 are perspective views of certain of the elements of my improved machine.

Referring to the drawings, 8 represents-a hollow base upon which is secured a bearing block 9. A stud shaft 10 is rotatively mounted in the bearing block 9 and at its upper end is screwed into a spider 11 hav ing arms 12 extending radially from said shaft 10, said arms having clutch jaws 13 respectively slidable thereon. The clutch jaws 13 are adapted to support a can or other vessel 14; each of the jaws having a lip 15 for engaging the side of the can. In the present instance the spider 11 includes four arms 12 arranged at right angles to each other and two' clamping screws 16 and 17 have threaded portions extending through oppositely disposed jaws; the threaded portions being oppositely pitched as clearly shown in Fig. 3. Each of the clamping screws has a central grooved portion 18 and these grooved portions intersect each other ate pinion 32. An agitator or mlxing paddle. 38 includes.

as shown in Fig. 3 so that the clamping screws are prevented from mo-vin'glongitudinally when they'are rotated to move the Patented Apr. 5. 1921. v

jaws toward or from the axisof the spider.

An electric motor 19 is'secured to the base 8 and has a beveled pinion 20'which meshes with a beveled gear 21 on a shaft 22. This shaft 22 has a pinion 23 at its lower end positioned w1th1n the base-8 and adapted to mesh with a gear wheel 24 secured to the stud shaft 10; said gear wheel 24 also being located within the base 8. A tubular stand ard 25 incloses the shaft 22 and is secured by means of a collar 26 to the base 8.

An arm 27 has a hollow hub 28 which is split at 29; said hub" embracing theupper portion of the tubular standard 25 as a pivot. A binding-screw '30 extends through the split portion ofthe hub 28 and can be operated to clamp the hub 28 to the standard'25. The shaft 22 extends through the arm 27 and has a pinion 31 on the top thereon; said pinion being in mesh with an intermediate pinion 32; said intermediate pinion having a trunnion 33 which is rotatably' mounted within a cavity 34 in the top of the arm 27.

The arm 27 has a hole 35 in which r0 tatably fits the hub 36 of a gear wheel 37. said gear wheel meshing with the intermeditwo substantially U-shape members 39 and 40; the head portions 41 and 42 of said members 39 and 40 being preferably secured transversely to each other by brazing or other suitable means. The prongs 43 of the members 39 and 40 are adapted to be slipped downwardly through slots 44 in the hub 36 of the gear wheel 37 so that said prongs extend into the can 14. A plate 44 is preferably secured to the bottom of the hub 36 of the gearfwheel 37 to prevent said gear wheel 37 from accidentally moving upwardly during the operation of the machine. It will be understood by the construction asabove described that the mixing paddle can be freely lifted, as a whole,.out of the can 14 and the arm 27 can be freely swung on the standard 25 as a pivot'after the binding screw' 30 has can be quickly removed or replaced.

By the arrangement of the driving means as above described it will be noted that when the motor 19 is started the can 14, and the material therein to be mixed, is rotated in one direction while the mixing paddle 38 is rotated in an opposite direction. By this means the material within the can can be quickly and thoroughly mixed. It will be also understood that, due to the pivotal mounting of the arm 27,.the paddle 38 can be swung into any position toward or from the inner surface of the can so that the material in all parts of the can can be thoroughly agitated and mixed.

The clamping screws 17 can be quickly operated so as to firmly hold the jaws 13 in engagement with the can 14.

While I have described my invention as taking a particular form it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A mixing machine including means for supporting a vessel in which material to be mixed is placed; a supporting structure; an arm on said supporting structure and adapted to be moved over and away from said vessel; movable means on said arm; and a mixing device freely suspended from said latter movable means into said vessel and having a portion resting on said moving means said portion being adapted to be manually grasped and lifted so as to move said mixing device out of the vessel without raising said arm and to permit said arm to be moved in a substantially horizontal path from over, said vessel; substantially as described.

2. A mixing machine including means for supporting a vessel in which material to be mixed is placed; a supporting structure; an arm on said supporting structure and adapted to be moved over and away from said vessel; movable means on said arm and having slots therein; and a mixing paddle having prongs depending through said slots into said vessel; substantially as described.

3. A mixing machine including means for supporting a vessel in which material to be mixed is placed; a supporting structure; an arm on said supporting structure and adapted to be moved over and away from said vessel; movable means on said arm and having slots therein; and a mixing paddle including a U-shape member having prongs depending through said slots into said yes sel; substantially as described.

4. A mixing machine including means for supporting a vessel in which the material to be mixed can be placed; a movable member adapted to be moved over and away from the top of said vessel and having holes therein spaced apart; and a mixing member having separated leg portions adapted to be re spectively slid through said holes in the movable member so as to depend, into said vessel, said movable member having a portion against which a part of said mixing member rests by gravity whereby the mixmg member is capable of moving with the movable member but can be readily lifted therefrom; substantially as described.

5. A mixing machine including a base; means supported by said base for rotatably supporting a vessel in which material tobe mixed is placed; a tubular standard mounted on said base; an arm pivotally mounted on said standard and movable in a substantially horizontal path over and away from said vessel; a gear wheel on said arm; mixing means connected to said gear wheel and depending into said vessel; a shaft extending through said tubular standard; a pinion on said shaft; a gear wheel operatively con, nected to said first means and in mesh with said pinion; a second pinion on said shaft; an intermediate pinion operatively connecting said latter pinion with said first mentioned gear wheel; and means for operating said shaft; substantially as described.

6. A mixing machine including a base; means supported by said base for rotatably supporting a vessel in which material to be mixed is placed; a tubular standard mounted on said base; an arm pivotally mounted on said standard and movable in a substantially horizontal path over and away from said vessel; a gear wheel on said arm; mixing means connected to said gear wheel and depending into said vessel; a shaft extending through said tubular standard; a pinion on said shaft; a gear wheel operatively con nected to said first means and in mesh with said pinion; a second pinion on said shaft; an intermediate pinion operatively connecting said latter pinion with said first men tioned gear wheel; and a motor mounted on said base and operatively connected to said shaft; substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
